Description

  The present invention relates to an X-ray diagnostic apparatus, and more particularly to a technique for improving operability when an operation unit is moved or detached.

  The top plate located at the top of the examination table of the X-ray diagnostic device has a rod-shaped rail that holds peripheral devices such as an electrocardiograph and an infusion table as well as an operation unit that operates the device. It is arranged. Since the type of peripheral device to be used and the fixing position suitable for use differ depending on the type of examination, the rail has a structure that allows the operator to fix the peripheral device at a desired position.

  In particular, in an X-ray diagnostic apparatus for angiography, an operation unit is often held on the rail. The top plate on which the subject is placed includes a lifting / lowering operation, a horizontal slide movement, a tilting operation such as tilting, and the operation unit held by the rail moves in the same manner as the top plate.

  In addition, when the subject is placed on or lowered from the top board, the operation unit is removed from the rail, or the position is shifted by sliding on the rail.

  On the other hand, there is provided a screening table in which a handle that can be moved by an operator's operation in each of a longitudinal direction, a short side direction, and a vertical direction can be placed at a position where it can be easily operated. In this examination table, the operator with the switch is structured so that it can move freely on the rail, and the operator is necessary by fixing the handle to the rail only when the switch that makes the top plate movable is pressed. When the handle is moved to a necessary place at any time and the top plate is moved, the handle is fixed to the rail, so that the function as the handle can be fully exerted (see, for example, Patent Document 1).

  However, conventionally, the operation unit is connected with a cable for transmitting / receiving information to / from the control unit and a power supply cable, and when the top plate of the examination table is moved or the operation unit is removed from the rail as described above, Cable obstructs movement / removal operation. On the other hand, when the transmission / reception of information between the operation unit and the control unit is performed wirelessly without using a cable, the operation unit is generally driven by a battery. In this case, a battery charging operation is always required after a predetermined period of use, which increases the burden on the surgeon. Further, when the battery is not charged, there is a problem that the operation unit cannot be used and emergency treatment cannot be performed.

  The present invention provides an X-ray tube that exposes a subject to X-rays, an examination table that includes a top plate on which the subject is placed, and an X-ray image that passes through the subject. An X-ray diagnostic apparatus comprising a line detector, comprising: an operation unit operated by an operator to give an operation instruction to the X-ray diagnostic apparatus; and a non-contact power supply unit that supplies electric power to the operation unit in a non-contact manner. It is to be prepared. In addition, the non-contact power supply means includes a power receiving unit disposed in the operation unit and a power supply unit disposed in a site where the operation unit is installed, and detects whether the operation unit is installed. Have means. Moreover, the said operation part is installed in a top plate. Alternatively, the operation unit is a foot switch installed on the floor. Therefore, the operation unit functions even when there is no power cable to be connected and a battery that needs to be charged.

  The operation unit is not a battery that needs to be charged but is supplied with power by non-contact power supply means, so there is no burden on the surgeon such as a charging operation. Moreover, since there is no unusable state due to uncharged battery, emergency response is possible. Furthermore, since the operation unit is detected when it is not set at the correct position, the operator can correct the position before the operation. In addition, if a wireless communication means for wirelessly transmitting and receiving input / output information of the operation unit is provided, there is no cable connected to the operation unit, and the operability can be improved when moving the top of the examination table or removing the operation unit from the rail. Will improve.
